Expand description A complete description of how to format and parse a type.
This enum is marked as non-exhaustive Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Bytes that are formatted as-is.
Note : These bytes should be UTF-8, but are not required to be. The value is passed
through String::from_utf8_lossy
when necessary.
A minimal representation of a single non-literal item.
A series of literals or components that collectively form a partial or complete
description.
A FormatItem
that may or may not be present when parsing. If parsing fails, there
will be no effect on the resulting struct
.
This variant has no effect on formatting, as the value is guaranteed to be present.
A series of FormatItem
s where, when parsing, the first successful parse is used. When
formatting, the first element of the slice is used. An empty slice is a no-op when
formatting or parsing.
